ObjectiveTo analyze rate of intraperitoneal lymph node metastasis (LNM) in Siewert type Ⅱ/Ⅲ adenocarcinoma of esophagogastric junction (AEG) so as to determine optimal extent of lymph node dissection. MethodsA systematic and comprehensive search of PubMed, Medline, and Cochrane Library databases for study reports on LNM in patients with Siewert type Ⅱ/Ⅲ AEG was performed. The retrieval time ranged from database establishment to October 1, 2021. The pooled LNM rate was analyzed for each lymph node group. In addition, the influencing factors of LNM in AEG were analyzed. ResultsAfter screening, a total of 22 relevant studies were included, with a total of 3 934 cases. For the patients with Siewert type Ⅱ/Ⅲ AEG, the LNM rates of No.1, 2, 1&2, 3, 7 lymph nodes were ≥20%, LNM rates of No.4, 9, 11 (11p+11d), 11p, 16 lymph nodes were 10%–20%, LNM rates of No.4sa, 8a, 10, 11d lymph nodes were 5%–10%, the rest were <5%. For the patients with Siewert type Ⅱ AEG, the LNM rates of No.1, 2, 1&2, 3, 7 lymph nodes were ≥20%, LNM rates of No.4, 9, 11 (11p+11d), 11p lymph nodes were 10%–20%, LNM rates of No.8a, 10 lymph nodes were 5%–10%, and the rest were <5%. For the patients with Siewert type Ⅲ AEG, the LNM rates of No.1, 2, 1&2, 3, 4, 7 lymph nodes were ≥20%, LNM rate of No.11p lymph nodes was 10%–20%, LNM rates of No.4sa, 4sb, 4d, 8a, 9, 10, 11(11p+11d), 11d lymph nodes were 5%–10%, and the rest were <5%. No matter Siewert Ⅱ and (or) Ⅲ AEG patients, the rates of LNM in No.5, 6, and 12a lymph nodes were <5%. The tumor diameter ≥2 cm and higher T stage (T2–T4) increased the probability of LNM in AEG (P<0.05). ConclusionsThe results of this meta-analysis combined with the literature suggest that in clinical practice, No.10 lymph node dissection is not necessary for Siewert Ⅱ and Siewert Ⅲ AEG patients with tumor length diameter <2 cm and T1 of tumor invasion. No matter Siewert Ⅱ or Ⅲ AEG, as long as the tumor length diameter <2 cm and T1 of tumor invasion, the distal perigastric lymph nodes (No.4d, 5, 6) may not be dissected; Siewert type Ⅱ or Ⅲ AEG patients don’t need to clean No.12a lymph nodes.
ObjectiveTo investigate the incidence, pathogens, risk factors and clinical outcomes for ventilator- associated pneumonia (VAP) in children after tetralogy of Fallot (TOF) surgical correction, in order to offer reliable data for the prevention of VAP.MethodsThis was a retrospective study performed in Guangdong General Hospital and 181 children (121 males, 60 females, mean age of 11.2±10.4 months) undergoing surgical correction for TOF were included. ALL the children who received mechanical ventilation for 48 hours or longer between January 2013 and December 2017 were classified into a VAP group (n=44) and a non-VAP group (n=137). T test, χ2 test and multiple logistic regression analysis were used to identify the possible risk factors for VAP.ResultsThis study enrolled 181 patients , of which 44 were diagnosed as VAP. And the incidence of VAP was 24.3%. The most frequent isolated pathogen was Gram-negative bacteria (69.7%). Single factor analysis showed that the variables significantly associated with a risk factor of VAP were: hypoxic spells, preoperative pneumonia, preoperative mechanical ventilation support, cardiopulmonary bypass (CPB) time, reintubation, pulmonary atelectasis, low cardiac output syndrome (LCOS), intra-abdominal drainage and transfusion of fresh frozen plasma. The multiple logistic regression showed CPB time (OR=1.011), reintubation (OR=14.548), pulmonary atelectasis (OR=6.139) and LCOS (OR=3.054) were independent risk factors for VAP in children after TOF surgical correction. Patients with VAP had prolonged duration of mechanical ventilation, a longer ICU stay and longer hospitalization time.ConclusionsThe VAP rate in this population is higher than that reported abroad, which leads to prolonged duration of mechanical ventilation and a longer hospital stay. The effective measures for prevention of VAP should be taken according to the related risk factors for VAP to decrease the incidence of VAP in children after TOF surgical correction.
ObjectiveTo investigate the risk factors of internal mammary lymph node (IMLN) metastasis in breast cancer patients, and to provide evidence for clarifying the TNM stage of tumors and formulating precise treatment plans. Methods The female patients who were admitted to the First Affiliated Hospital of Chongqing Medical University from February 2019 to January 2020 and diagnosed with breast cancer by tissue biopsy pathology based on the new tracer technology were retrospectively collected. All IMLNs were dissected. The associations of IMLN metastasis with patients’ age, tumor size (long diameter), tumor location, tumor grade, estrogen and progesterone receptor statuses, human epidermal growth factor receptor-2 (HER2) status, number of axillary lymph node (ALN) metastasis, and pathological molecular typing were analyzed. ResultsA total of 28 patients were included in this study. The visualization rates in the ALN and IMLN by the new tracer technique were 96.4% (27/28) and 35.7% (10/28), respectively. The pathological results of IMLN biopsy confirmed that 6 patients (The 6 cases were all displaying) had IMLN metastases, with an IMLN metastasis rate of 21.4%. The IMLN metastasis was related to the tumor location and ALN metastasis number of patients with breast cancer (P<0.05). That is to say, when the tumor located in the medial quadrant and the number of ALN metastasis was 4 or more, the IMLN metastasis rates were higher than those in the lateral quadrant (57.1% vs. 10.0%, P=0.028) and in the patients with ALN metastasis number <4 (50.0% vs. 11.1%, P=0.038). It was not found that IMLN metastasis was related to age, tumor size, tumor grade, estrogen and progesterone receptor statuses, HER2 status, and pathological molecular typing of patients with breast cancer (P>0.05). And the area of the receiver operating characteristic curve of the number of ALN metastasis for assessing IMLN metastasis was 0.697. ConclusionFrom the summarized results of cases in this study, the visualization rate of IMLN is higher based on the new tracer technology. When breast cancer locates in the medial quadrant and the number of ALN metastasis is 4 or more, it is recommended to actively carry out IMLN biopsy to clarify the results of pathological diagnosis, so as to accurately assess the tumor stage and formulate appropriate individualized treatment plan.

Objective To analyze the clinical characteristics of the Guang’an Omicron epidemic and summarize the management experiences and practices in pandemic prevention and control of major infectious diseases.Methods Retrospective analysis was performed on patients infected with coronavirus disease (COVID-19), afterwards treated and observed in the isolation ward of Guang’an People’s Hospital and the shelter of Guang’an City from May 9 to June 26, 2022. The characteristics of patients at different age stages and the related factors affecting the severity, re-positive and negative conversion was analyzed. Results Finally 1 278 patients were collected, including 508 males and 770 females, with an average age of 41.3±22.6 years. Among them, 1 054 patients were asymptomatic carriers. The overall severe rate was 0.86%, the severe rate of the high-risk group was 3.06%. The median negative conversion time was 10.0 days and re-positive rate was 7.36%. Patients aged＞60 years were 2.589 times more likely to have a longer negative conversion time than those aged≤60 years (95%CI 1.921-3.489, P＜0.001). Conclusion The clinical characteristics of Guang’an COVID-19 epidemic are mainly that the elderly with high risk factors are more likely to develop severe cases, have longer clearance time, and re-positve is more likely to occur.
ObjectiveTo analyze the risk factors for postoperative mortality of the elderly patients with femoral neck fracture undergoing hemiarthroplasty.MethodsPatients who underwent hemiarthroplasty for femoral neck fractures between January 2011 and December 2015 were enrolled as object. One hundred and nine patients who met the selection criteria were included in the study, and the clinical data were collected, including gender, age, time from admission to surgery, comorbidities, and preoperative hemoglobin level and nutritional status. Univariate analysis and Cox proportional hazard regression model were used to screen the risk factors for postoperative mortality.ResultsThe 1-year and 2-year mortalities were 6.4% (7/109) and 17.4% (19/109), respectively. Univariate analysis showed that the age, preoperative hemoglobin level and nutritional status were the influencing factors of postoperative mortality in the elderly patients with femoral neck fractures treated with hemiarthroplasty (P<0.05). Multivariate analysis showed that the age≥80 years and malnutrition were the independent risk factors for postoperative mortality (P<0.05).ConclusionTo improve the clinical outcomes, perioperative risk should be comprehensively evaluated by multidisciplinary and perioperative management should be strengthened in the elderly patients with femoral neck fracture, especially those with advanced age and malnutrition, for the high postoperative mortality.
ObjectiveTo clarify the risk factors of diaphragmatic dysfunction (DD) after cardiac surgery with extracorporeal circulation. MethodsA retrospective analysis was conducted on the data of patients who underwent cardiac surgery with extracorporeal circulation in the Department of Cardiovascular Surgery of Peking University People's Hospital from January 2023 to March 2024. Patients were divided into two groups according to the results of bedside diaphragm ultrasound: a DD group and a control group. The preoperative, intraoperative, and postoperative indicators of the patients were compared and analyzed, and independent risk factors for DD were screened using multivariate logistic regression analysis. ResultsA total of 281 patients were included, with 32 patients in the DD group, including 23 males and 9 females, with an average age of (64.0±13.5) years. There were 249 patients in the control group, including 189 males and 60 females, with an average age of (58.0±11.2) years. The body mass index of the DD group was lower than that of the control group [(18.4±1.5) kg/m2 vs. (21.9±1.8) kg/m2, P=0.004], and the prevalence of hypertension, chronic obstructive pulmonary disease, heart failure, and renal insufficiency was higher in the DD group (P<0.05). There was no statistical difference in intraoperative indicators (operation method, extracorporeal circulation time, aortic clamping time, and intraoperative nasopharyngeal temperature) between the two groups (P>0.05). In terms of postoperative aspects, the peak postoperative blood glucose in the DD group was significantly higher than that in the control group (P=0.001), and the proportion of patients requiring continuous renal replacement therapy was significantly higher than that in the control group (P=0.001). The postoperative reintubation rate, tracheotomy rate, mechanical ventilation time, and intensive care unit stay time in the DD group were higher or longer than those in the control group (P<0.05). Multivariate logistic regression analysis showed that low body mass index [OR=0.72, 95%CI (0.41, 0.88), P=0.011], preoperative dialysis [OR=2.51, 95%CI (1.89, 4.14), P=0.027], low left ventricular ejection fraction [OR=0.88, 95%CI (0.71, 0.93), P=0.046], and postoperative hyperglycemia [OR=3.27, 95%CI (2.58, 5.32), P=0.009] were independent risk factors for DD. ConclusionThe incidence of DD is relatively high after cardiac surgery, and low body mass index, preoperative renal insufficiency requiring dialysis, low left ventricular ejection fraction, and postoperative hyperglycemia are risk factors for DD.
ObjectiveTo summarize the early clinical features and perioperative management strategies for patients with transposition of the great arteries (TGA) after one-stage arterial switch operation (ASO), and investigate the risk factors for prolonged recovery in ICU, with a focus on the age structure and deformity complexity.MethodsThe clinical data of 231 consecutive TGA patients who underwent one-stage ASO were retrospectively analyzed. There were 165 males and 66 females, aged from 3 d to 10 years. The patients were sequenced by the length of ICU stay. The time at the 75th percentile was defined as the critical value for grouping. Patients with an ICU stay time over this point were allocated to a prolonged recovery group (n=54), while the rest were allocated to a normal recovery group (n=177). The perioperative clinical data were compared between the two groups, and the risk factors for prolonged recovery were evaluated.ResultsAbout half (49.6%) of the patients received late operation. The mean ICU stay time was 23.9±15.6 d in the prolonged recovery group, and 4.9±2.3 d in the normal recovery group. Complication of aortic arch lesion, delayed chest closure and postoperative pulmonary infection were independent risk factors for prolonged recovery after ASO in ICU. However, late operation had no significant effect on the overall recovery.ConclusionWith strict surgery indications and excellent postoperative management, most patients can have satisfactory early-stage outcomes, but are confronted with increased complications, which is associated with prolonged recovery. Complication of aortic arch lesion, delayed chest closure and postoperative pulmonary infection are independent factors for delayed recovery of ASO.
ObejectiveTo summarize the research progress of risk factors contributing to postoperative pulmonary infection in gastric cancer, so as to provide reference for medical decision-makers and clinical practitioners to effectively control the incidence of postoperative pulmonary infection in gastric cancer, ensure medical safety and improve the quality of life of patients. MethodThe researches at home and abroad on the factors contributing to pulmonary infection after gastric cancer surgery in recent years were reviewed and analyzed. ResultsThere was currently no uniform diagnostic standard for pulmonary infection. The incidence of postoperative pulmonary infection for gastric cancer varied in the different countries and regions. The pathogenic bacteria that caused postoperative pulmonary infection of gastric cancer was mainly gram-negative bacteria, especially Pseudomonas aeruginosa, Escherichia coli, Acinetobacter boulardii, and Klebsiella pneumoniae. The patient’s age, history of smoking, preoperative pulmonary function, preoperative laboratory indicators, preoperative comorbidities, preoperative nutritional status, preoperative weakness, anesthesia, tumor location, surgical modality, duration of surgery, blood transfusion, indwelling gastrointestinal decompression tube, wound pain, and so on were possible factors associated with postoperative pulmonary infection of gastric cancer. ConclusionsThe incidence of postoperative pulmonary infection for gastric cancer is not promising. Based on the recognition of related factors, it is proposed that it is necessary to develop a risk prediction model for postoperative pulmonary infection of gastric cancer to identify high-risk patients. In addition to the conventional intervention strategy, taking the pathogenesis as the breakthrough, finding the key factors that lead to the occurrence of postoperative pulmonary infection of gastric cancer is the fundamental way to reduce its occurrence.
Objective To investigate the risk factors for delayed discharge following same-day choledochoscopic lithotomy for residual stones after biliary tract surgery. Methods The clinical data of 607 patients with residual stone after biliary tract surgery admitted to the Day Surgery Center of West China Hospital of Sichuan University between July 2019 and July 2022 were retrospectively collected. According to whether the patients were discharged on the same day, they were divided into same-day discharge group and delayed discharge group. The differences in gender, age, first surgical procedure (surgical method, hepatectomy or not, intraoperative choledochoscopy or not), choledochoscopic lithotomy (first choledochoscopy or not, lithotomy method, number of stones and site of stones), operation duration, hospital stay, hospital cost, and postoperative complications (fever, poor drainage, and T tube dislodgement) between the two groups were compared and analyzed. Multiple logistic regression model was used to analyze the risk factors for delayed discharge following same-day choledochoscopic lithotomy. Results All patients were admitted and discharged within 24 h, among them, 557 cases (91.8%) were discharged on the same day and 50 cases (8.2%) were discharged the next day. The results of multiple logistic regression analysis showed that choledochoscopy for the first time [odds ratio (OR)=2.359, 95% confidence interval (CI) (1.303, 4.273), P=0.005], lithotomy after electrohydraulic lithotripsy [OR=1.857, 95%CI (1.013, 3.402), P=0.045], and multiple stones (number of stones ≥2) [OR=2.741, 95%CI (1.194, 6.288), P=0.017] were independent risk factors for delayed discharge. Conclusion The operation of same-day choledochoscopic lithotomy is mature, and choledochoscopy for the first time, lithotomy after electrohydraulic lithotripsy, and multiple stones (number of stones ≥2) are independent risk factors for delayed discharge.
